Intervention The intervention for the group MEDIA is a "keeping in touch" intervention through sending of SMS (or mail or other new media). The patient will receive 6 SMS (or mail or other new media) during 6 months after the SA. The first one 7 days after the SA and the last one after 6 months. The first SMS (or mail or other new media) is sent soon after the SA because studies on adult suicide attempters underline the importance of an early start for the connectedness measures. The text messages are evolving in time, and are adapted to the genre of the adolescent.
